So the mystery performer at the pre-NBA All-Star Game Concert this week isn't going to be Rihanna—it's actually going to be her collaborator and awards show stage crasher Kanye West. Better hide your Beck albums, Flatiron residents!

The concert is being produced by Jay Z's Roc Nation, and it's called the 1st Roc City Classic. There had been worries that it would cause some commotion, so Roc Nation sent an email outlining what's going to happen:

TO RESIDENTS AND BUSINESSES IN THE FLATIRON DISTRICT:

Starting at 6:00 p.m. on Thursday, February 12th, Broadway and Fifth Avenues, between 23rd and 26th Streets will be closed to vehicular traffic by NYPD, for the assembly of the audience.

Now we're wondering if RiRi and a whippersnapper/ELO fan named Paul McCartney might be joining in:
